Handlers typically process SOAP headers or perform other types of system-level functions (logging, monitoring, authentication, signature verification, etc.)
You specify what method should be invoked for each operation type in the WSDD.
If you want to do your own request routing, then you probably want to build a custom "provider". A provider is responsible for taking the message after the handler chain is complete, transforming the SOAP body from XML into Java and invoking a Java object.
Axis supplies three providers: - RPC - EJB - MSG
The RPC provider performs automatic marshalling and demarshalling of the SOAP messages and invokes Java objects. The EJB provider performs automatic marshalling and demarshalling of SOAP messages and invokes stateless session beans. The MSG provider converts the SOAP message into a DOM and invokes a Java object.

hey friends,
In my application I will get a series of SOAP requests. All I need to know is: 1. How do I write a general Soap request handler (like a controller), All the reqest should be handled here like a centralized controller. 2. The controller should scan through the request types, based on that it should invoke the appropriate web-service (like action classes) - how to do ? 3. Those webserivces will do all the required validations and finally invoke my EJB's on JBoss (Like Model in MVC). 4. EJB's return the response data, webservice will generate the response object, give it to controller and finally controller returns the result to client.
I looked at the API's but still confused: 1. org.apache.axis.handlers.soap - When should i use this ? 2. org.apache.axis.handlers.http - When should i use this ?
In struts or any mvc framework, we map the request uri to a particular action classes, how do we do that in Web services?
help me in creating a framework ! cheers -kannan
